I do fine winter or summer because we have a/c and use our ceiling fans in every room run constantly. However, last year I started having hot flashes and just could not do the handwork on my son's quilt with the high loft batting in it. So I can see where there may be times when it is too hot to quilt with a big hot quilt on your lap. But like others have said there's always hand work. I'm one who does not like to run the iron though when it's too hot so if I can't work on things that require ironing early when it's cool, I work on other things that don't heat up my little house.
